During the last decade, airborne laser scanning has become a widely applied method for accurate estimation and mapping of biomass at local to regional scales. However, mapping of biomass at a global scale would be prohibitively expensive with this approach.
In an effort to utilize the laser methodology also for the global level mapping of biomass, NASA recently mounted a laser instrument on the International Space Station. The mission is called GEDI (Global Ecosystem Dynamics Investigation) and has been in operation since December 2018.
SLU has contributed to the statistical methods used for estimation and mapping of biomass and the related uncertainties through hybrid and hierarchical model-based inferential methods.
Speaker is Svetlana Saarela, Associate Senior Lecturer at the Department of Forest Resource Management, SLU.
